技术领域technical field
本实用新型涉及医疗器械术领域，具体是一种冲洗式引流管。The utility model relates to the field of medical equipment, in particular to a flushing drainage tube.
背景技术Background technique
放置引流管是临床手术后为预防患者手术区残留坏死组织或感染灶、发生吻合口瘘或残端漏、手术创伤大估计渗液多而施行的最常见的操作之一。目前临床常规使用的引流管为内套管与外套管可拆分式的传统双套管，且内套管为材质较坚硬的塑料材质，体外部分内外套管需要再次固定，使其连接处不能严密结合，易导致引流液外渗污染引流管穿透皮肤处切口。同时，内套管固定不牢，易随患者体位变化而活动，向外脱出体外，而向内则会通过外套管引流孔穿入引流部位而损伤引流部位周围脏器、血管及神经等，造成因引流引发的二次损伤，甚至可危及患者生命安全。在传统引流管中，外套管引流孔易被引流部位周围组织阻塞而使引流不够通畅，不能有效达到留置引流管的目的。若引流部位为腹腔，大网膜及小肠活动范围较大，更容易进入到引流孔甚至阻塞内套管内口，亦对术后通过引流管冲洗造成困难。而质地较硬的内套管亦会在引流浅表部位时造成患者的不适感。Drainage tube placement is one of the most common operations performed after clinical surgery to prevent residual necrotic tissue or infection foci in the surgical area, anastomotic leakage or stump leakage, and large surgical trauma and excessive exudate. At present, the drainage tube commonly used in clinical practice is the traditional double cannula with detachable inner cannula and outer cannula, and the inner cannula is made of relatively hard plastic material. Tight combination can easily lead to extravasation of drainage fluid and contamination of the incision where the drainage tube penetrates the skin. At the same time, the inner cannula is not fixed firmly, and it is easy to move with the change of the patient's position, and it will protrude out of the body outwardly, while inwardly, it will penetrate into the drainage site through the drainage hole of the outer cannula and damage the surrounding organs, blood vessels and nerves of the drainage site, resulting in The secondary injury caused by drainage may even endanger the life of the patient. In the traditional drainage tube, the drainage hole of the outer cannula is easily blocked by the surrounding tissues of the drainage site, so that the drainage is not smooth enough, and the purpose of indwelling the drainage tube cannot be effectively achieved. If the drainage site is the abdominal cavity, the greater omentum and small intestine have a larger range of motion, and it is easier to enter the drainage hole or even block the inner opening of the inner cannula, which also makes it difficult to flush through the drainage tube after surgery. And the hard inner cannula will also cause discomfort to the patient when draining superficial parts.
